We collected data from almost 18,000 myAir users who were asked to self-assess their daytime sleepiness on a 5-point scale before starting therapy. These myAir users were then asked again every week for 4 weeks to self-assess their daytime sleepiness.

Please refer to the myAir support for relevant information related to any warnings and precautions to be considered before and during use of the product.
